-----------------------------------

             Summary: Currently the ranger-admin will be aborted when the exception occured.
We should get the default value instead of aborted.
                 Key: RANGER-1280
                 URL: https://issues.apache.org/jira/browse/RANGER-1280
             Project: Ranger
          Issue Type: Bug
          Components: admin
            Reporter: Qiang Zhang
            Assignee: Qiang Zhang


I failed to run the ranger-admin command and couldn't find any error messages in log file
after set ranger.service.http.connector.attrib.maxHeaderCount=aa(string value) in ranger-admin-site.xml
file. I analyzed the source codes and found the reason.
I found there are two questions after check the source codes in EmbeddedServer.java.
1. No exception pop out when called Integer.parseInt() and Long.parseLong() function. Once
abnormal, the program aborted directly without log.
2. The catch captures anomaly without log in the loadConfig function. It only calls e.printStackTrace()
function.

Currently the program will be aborted when the exception occured. We should get the default
value instead of aborted.
